Answer:
25% decrease
Step-by-step explanation:
Percent change can be found by doing difference/original
(950,000 - 712,500) / 950,000
= 0.25
There was a 25% decrease in the population
<u>Given</u>:
The given expression is 
We need to multiply the terms.
<u>Multiplication of the terms:</u>
Before multiplying the terms, first we shall find the factors of the quadratic equations.
Thus, we have;

Factor out the common terms, we get;

Let us cancel the common terms from the above expression.
Thus, we have;

Simplifying, the term, we get;

Now, we shall multiply the terms.
Hence, multiplying the terms, we get;

Thus, the multiplied value of the given expression is 
V initial = 0
v final = 1920 m/s
t = 3 2/3 mins = 220s
d = ?
d = 1/2(vi + vf)t
d = 1/2((0)+(1920))(220)
d = 211200m
0.4215, 0.025, 0.001, 0.221
